Humans like to portray themselves as a sophisticated life form driven by brain rather than brawn. So they may be surprised by a project to reconstitute a 28,000-year-old skull from remains found in France.
This has provided evidence to support a theory that our brains have begun to shrink.
The French team that claims to have produced one of the best replicas yet of an early modern human skull say that it is 15 to 20 per cent bigger than ours. No one suggests that we are 15 to 20 per cent more stupid than Cro Magnon 1, the best preserved of five skeletons discovered in 1868 in the Cro Magnon cave in the Dordogne, because there is only a minor link between brain size and intelligence.
It may be that, rather like computers, our brains are becoming more efficient even as they grow smaller. But the project could shed light on a human evolutionary question that has divided and bemused the specialists: if indeed our heads have started to shrivel, why is this happening?
Cro Magnon 1 has been kept in the French National Museum of Natural History in Paris. He is believed to have been a well-built, elderly man about 6ft tall. Already known to scientists worldwide, Cro Magnon 1 will become even more famous next week when a mold of his skull will be shown at the American National Museum of Natural History in Washington.
